BOARD-FILLING MACHINE.

Application filed October 8, 1923. Serial No. 667,348.

To all whom t may conc-cwi.:

Be it known that I, 1WILLIAM P. STRIGK LAND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful improvement in Board-Filling Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in board-filling machines, and is fully described and explained in the specification and shown in the accompanying drawings, in which* Figure l is a view in front elevation of one form of machine constructed in accordance with my invention and showing the parts thereof in the position they assume during the charging of the strip-magazine with indicia-bearing strips which may be of paper and are to be severed into sections and thereupon introduced into the rows of holes in the board to be filled.

, As a preface to the-following description of the machine and its operation, it may be stated that the boards to be charged, one such board being represented at 35, contain, in their upper surfaces, in accordance with common practice, series of parallel rows of holes 36 and in their lower sufaces series rof parallel rows of Aholes 36a, the latter registering respectively with the former, though it will be understood that the machine may operate on boards wherein the` holes to be charged extend entirely through theboard.

Referring to the construction ofmachine illustrated in Figs. V1 to 19 inclusive, the frame of the machine is shown as formed of a table top'portion 30 supported on legs' opposite edges, with circumferential series of apertures 4l in which" radially-extending pins 42 are located, these pins, which are slidable radially in the openings 41, being provided at their inner ends with heads 43 which, in the position of the pins shown in Fig. 8, abut the inner surfaces of the drums in which they are slidable, the pins 42 in this position extending radially beyond the circumference ofthe drums, the'pins 42 of each series thereof being equidistantly spaced rapart a distance equal to the distance between adjacent rows of the holes 36-36a, and the several circumferential rows of these pins being so positioned that they will register with certain of the holes 36a' in each row thereof, whereby the board is adapted to be moved lalong the table top through the medium of the pins 42 entering the apertures therein,when the drums 39 are rotated as hereinafter described, it

being noted, in this connection, that byproviding mechanism for feeding the board, which operatesV to effect the feed by extending into the holes 36a in registration with the holes 36 for receiving the indicia-bearving strip sections the feeding of the board, to cause the holes 36 therein to be brought into theV desired registration with themechanism' which feeds the strip sections into these holes and hereafter described,`is accurately performed. The p-ins 42 are normally held in the position shown in Fig. 8, by means of springs 44, lshown as leaf springs, which are secured at one end to the drum, as indicated at 45, Yand engage at their opposite ends with heads 43 ofthe pins with which they cooperate. The` pins 42 are spring-pressed in order that the ones thereof which are at theupper port-ions of the drum 39 when the board is introduced into the machine before filling of the holes 36therein begins and also after the last row Y `ofholes in the board have been filled (the board at its opposite ends having imperforate portions) may recede under the force exerted against them by the board.` It is, however, desirable, when the pins 42 extend into holes 36a in the board after feeding the latter, that at least a portion'of these particular pins be heldV rigid, and to'this end ,I provide a pair of levers 46 of general bellcrank form which are pivoted at their angles, as indicated at 47, on a wall of the slot 4() (Figs. 7 and 8), these levers extending crosswise of the machine and each bcing provided at its arm 48 with an upwardly-extending stud 49 having a cone-shaped upper end adapted to enter a similarly shaped recess 50 in the under side of the head 43, it being understood that all of the heads 43 of the two intermediate circumferential rows of pins 42 are provided with the recesses referred to. The other, depending, arms 5l of the levers 46 are connected together by a. coil spring 52 tending to rock these levers in opposite directions to lower their arms 48. (lo-operating with the levers 46, at the arms 48 thereof, is a wedge-bar 53 which extends lengthwise of the machine and is guidingly supported to reciprocate between the arms 5l adjacent to which latter the wedge surfaces 54 of the bar extend. In the position of the bar 53 shown in Fig. 5, this bar has been moved to the right to extreme position, in which position the levers 4G engage at their studs 49 with the heads and rigidly hold the pins carried thereby against downward displacement, it being understood that the only pins which are thus rigidly held are the uppermost ones of the intermediate longitudinal series thereof. The wedge-bar 53 carries a roller 55 mounted on a stud 5G carried by this bar, this roller co-operating with a cam 57 secured to a shaft 58 jonrnaled in bearings 59 depending from the table top 30 and driven as hereinafter described, the rear end of the rod 53 being slotted, as indicated at 60, through which slot the shaft 58 extends. The spring 52 tends to move the rod 53 to the left in Fig. 5, thereby holding the roller 55 against the periphery of the cam 57, it being understood that the rod 53 will be held in the position shown in Fig. 5 at all times, except when the depressed portion (il of the cam 57 opposes the roller 55 and when this occurs, the rod 53 shifts to the left in Fig. 5 and permits the spring 52 to rock the levers 4G to a position in which the studs 49 of the latter are lowered to a position in which they do not interfere with the depressing of the pins 42 directly above them. It may be here stated that the parts of the machine are so constructed and arranged that t-he depressed portion 6l of the cam 57 opposes the roller 55, and the bellcranls 46 consequently are withdrawn from pin-engaging position, during the rotation of the drums 39, by the intermittently-operating mechanism hereinafter described, and, furthermore, that at the end of each cycle of operations hereinafter described and at which time the machine automatically l) ll lll) the machine forfilling, or the filled board, to be withdrawn from the machine.

In themovement of the levers 46 into engagement, at their tapered studs 49, with the conical recesses 50 in the pins 42, `a centering action on the 'drums occurs, the drums in this centering action being free to slightly rotate, vand thus accurate positioning of the drums relative to the mechanism, hereinafter described, for introducing the strip sections into the board, is effected.

Co-operating with the board 35, and serving as a means for yieldingly pressing the latter downwardly and firmly against the tcp 80, is a roller 62 mounted on a shaft 63 rotatably supported at its ends in rearwardly-extending arms 64 pivotally connected at 65 with` lugs 66 depen-ding from the base member 67 of a housing 68 surmounting the top 8O at posts, represented at 69, the arms 64 being connectedtogether, between their ends, by a cross-bar 7 O to which the head 71 on the lower end of a rod 72 is pivotally connected. The rod 72 extends upwardly into the housing 68 through an opening 78 in the base 67 thereof, and is surrounded by a coil spring 74 which bearsat its lower end against the head 71 and at its upper end against a collar 75 surrounding t-he rod 7 2 and movable up and down thereon, the collar 75 abutting, under the tension of the spring 74, the under side of a stud 76 rigidly secured to a standardV 77 rising from the base plate 67, the parts just described being so proportioned and arranged that when the board 35 vis interposed between the roller 62 and the top 80, the spring 74 will be under tension and cause this roller to bear with the de sired force downwardly against the board. rlhe roller 62 is adapted to be raised, against the action of the spring 74, at the will of the operator, through the medium of a shaft 78 ournaled in the sides of the housing 68, this shaft being provided at its outer end with a hand lever 79 and between its ends with a cam 80 which extends directly beneath, and in engagement with, av spring strip 81 mounted at one end on a shaft 82 journaled in the housing 68 to rotate there in, the other, free, end of the strip 81 containing an aperture through which the upper end of the rod 72 extends, the portion of this rod which extends above the strip 81 being provided with nuts forming a shoulder extending above the strip. When the lever 79 (Fig. 2) is rotated in counter clockwise direction therein, the cam 80 op erates to lift the free end of the strip 81 which, in engaging with the shoulder 83, raises the rod 72, and copsequently the roller 62 against the action of the spring 74.

rEhe feeding drums 39 are rotated inten niittently to cause the vboard to feed through the 'machine by a step-by-step motion, by means of the driving mechanism of which the following is a description: @ne end of the shaft 37 is provided with a ratchet 84 rigid thereon ('Fig. 15) which cooperates with a pawl 85 shown as in the form of a bent lever pivotally supported between its ends, as indicated at 86, on a reciprocating rod 87 and having a tooth 88 cooperating with the ratchet 84, the rear end of the pawl lever being connected with a spring 85'LL attached to the /machine and operating to vieldingly hold this pawl in engagement with the ratchet 84. The paw] 85 is caused to rotate the ratchet 84 a distance of one tooth, in counter-clockwise direction in Fig. 15, each time the rod 87 makes a complete reciprocation. The rod 87 contains in its forward end a slot 89 at which it surrounds the shaft 37, the latter forming a guide for the rod 87. The rear end of the rod 87 is slotted, as indicated at 90, at which it surrounds a shaft 91 j ournaled in bearings depending from the under side of the top 30 and driven as hereinafter described, this shaft having rigid thereon a cam disk 92 and a collar 92a, the lower portion of the cam surface of the disk 92 being represented at 93. The cam-disk 92 cooperates with a roller 94 journaled on a stud 95 carried by the rod 87 a coil spring 96 connected at one end, as indicated at 97, to the top 30 and at its upper end, as indicated at 98, to the rod 87 operating to hold the roller, 94 at all times in engagement with the peripheral cam surface of the cam 92. The collar 92 is provided with a radially projecting lug 92b and the rear end of the pawl-lever 85 bears upwardly against the periphery of the collar 92a. It will be understood from the foregoing that in the rotation of the cam 92 the rod 87 will be given an intermittent reciprocating movement and in each complete reciprocation will partially rotate the ratchet 84 and thereby actnate the beard-feeding drums 39.

Means are provided for arresting the feeding of the board by the drums 39, at the will of the operator, these means comprising a lever 99 fulcrumed at 100 on the top portion 30 of the frame, one end of this lever, represented at 101, being accessible for operation by the operator and the other end thereof being.;Y provided with a pin 102 which extends under the tooth portion 88 of the pawl 85, and, when the lever 99 is rocked in clockwise direction in Fig, 15, rocks the pawl out of engagement with the ratchet 84. rlhe machine .is provided with means whereby the step-by-step feeding of the board by the mechanism described may be regulated to vary the length of movement of the board with each feeding operation, to the end that the board may be fed a distance equal to the distance between the centers of adjacent rows of the holes therein to be filled or twice or three times the distance between centers of adjacent holes in the board to be -filled whereby the holes 86 in the board may be filled, by the mechanism hereinafter referred to, in Vregular order, or by skipping one or more rows with each feeding operation as desired. The means shownY for this purpose comprise a disk 103 provided on its periphery with a series of step surfaces 104 faces 104 and'105 are in. direct line with the lug 106. lhen the circular periphery of this disc is in line with this lug, the rod 87, when the depressed surface 98 of the cani opposes the. roller 94, is free to move to the left iii Fig. 15, under the action of the spring 96, adistance sufficient to cause the pawl 85 to be preliminarily positioned, relative to the ratchet 84, for rotating the latter a distance of one tooth. In this adjustment the board is fed a distance equal to the distance'bet'ween centers of adjacent holes in the Vboard to be filled. lhen the disk 103 is rotated to a position in which the step surface 104 is in line with the lug 106, the rod 87 is free to move to the left in Fig. 15 a distance sufficient to cause the ratchet to beY when. the disc 108 is rotated to cause the step surface 105 to be in line with the lug 106 the bar 87 is permitted to move to the left in Fig. 15 sufiiciently far to position it for rotating the ratchet 84 a distance of three teeth thereof for causing the board to feed a distance equal to three times the distance between adjacent rows of holes therein, thereby causing the skipping of two rows with each board-feeding operation.

tically-extending Referring now to the mechanism for inserting the strip-sectioiis into the holes 36 in the board the side walls of the housing 68 are provided with forwardly-projecting arms 107 i containing upwardly-opening slots 108 adapted to receive the laterallyeXtending studs 109 on a removable and re- I ofplaceable magazine 110 for the strips to be their upper and lower ends for 'receiving the indicia-bearing strips, the front side of the magazine 110 being provided with a plate 114 of transparent material, as, for example, glass, which is preferably slightly spaced from ribs 113 and forms the front wall of the pluralities of strip-receiving grooves referred to, this plate being shown as held in place by clips 115 on the frame 111. The magazine 110 is provided, below the studs 109, with laterally-extending studs 116 adapted to be releasably engaged by rock levers 117 mounted between their ends on a shaft 118 journaled in the housing 68. Coil springs 119 are interposed between the rear ends of the levers 117 and the base plate of the housing 68 and tend to rock these levers downwardly at their outer ends. Journaled in the housing 68, in a plane above the levers 117, is a shaft 120 provided with a handle 120H, this shaft carrying cani lugs 120D disposed directly above the rear ends of the levers 117 and operating when the shaft 120 is rotated to rock the levers 117 against the resistance of the springs 119, to

a position in which these levers are disengaged from the studs 109 when it is desired to remove the magazine from the machine. The magazine 110 is provided with shearing mechanism forslieariiig the strips therein, into sections, when the strips are advanced through the magazine, as hereinafter described, to a certain position therein, the shearing` mechanism referred to comprising a shearing bar 121 fiatwise opposing the under side of a cross-bar 122 provided across the lower end of the Vmagazine and containing a horizontal series of apertures 123 extending entirely therethrough and in alignment with the channels provided between the ribs 118, these apertures Haring slightly upwardly. The shearing bar 121 which is located adjacent thel forward edge portion of the cross-bar 122, contains at its opposite end portions, openings 124 into which dcpeiidiiig crank-pins 125 provided on disks 126, extend, the disks 126 being rotatably confined in openings 127 in the cross-bar 122, and fixed on the lower ends of shafts 128 journaled in the side portions 111 of the magazine, the crank-pins 125 which, when the shafts 128 are rotated, operate the shearing blade 121 as hereinafter described, being preferably disposed in different angular positions, as shown. The upper ends of the shafts 128 are provided with discs 129 having laterally-extending arms 180 which, uuder the action of coil springs 131 surrounding the rods 128 and interposed between shoulders on the side portions 111 of the magazine 110, andthe discs 129, tend to bear rearwardly against the forward ends of push bars 182 slidably mounted in the front wall 188 of the housing 68, the rear ends of these rods being slotted, as indicated
